Word Graph
Objective: To introduce the field of Graph Theory to the students by working out an example and then defining proper terminology associated with the graph. Materials Needed: printout of Graph Theory worksheet or worksheet projected on screen.
Activity Suggested Time Materials Preparation
Introduction to activity
5 minutes Graph Theory Worksheet (can be downloaded at the website)
Hand out worksheet and have students read through instructions. Mention that this is a branch of mathematics that people study.
Work on Graph 20 minutes Have students work on the worksheets independently and help those who struggle with the concept.
Discussion 10 minutes Board space to write discussion
See below
Terminology 20 minutes Paper/Journal See below Wrap Up 5 minutes Collect material. The
students just got a taste of graph theory! Math can be fun!
Welcome Introduction to Activity [5 minutes] There are many branches of mathematics and some branches are not taught in typical K-12 classrooms. Studying this topic gives students a chance to expand their awareness in mathematics and handle different forms of math, not just what is covered in traditional math courses. Discussion [10 minutes] Ask the students what their graph looks like. Also does their graph look similar or different from their neighbor’s? Ask them if they think that all graphs are same or different and particularly look for different classification schemes. This would just be an out of the box discussion about how you can define ‘equivalence’ in terms of graphs. Help the students realize that math has a creative aspect that goes far beyond computations. Terminology [20 minutes]

This type of graph consists of vertices and edges. Vertices are objects (in our case the words) and edges are the lines that connects the vertices. Two graphs are isomorphic if the vertices and edges are the same. In other words, if two vertices are joined by an edge, then the other graph should have exactly that as well.
